STDAPI_(JsErrorCode)
    JsGetArrayBufferStorage(
    _In_ JsValueRef arrayBuffer,
    _Outptr_result_bytebuffer_(*bufferLength) BYTE **buffer,
    _Out_ unsigned int *bufferLength);

• arrayBuffer: The ArrayBuffer instance.
• buffer: The ArrayBuffer's buffer. The lifetime of the buffer returned is the same as the lifetime of the the ArrayBuffer. The buffer pointer does not count as a reference to the ArrayBuffer for the purpose of garbage collection.
• bufferLength: The number of bytes in the buffer.

The code JsNoError if the operation succeeded, a failure code otherwise.
